29	! 4709 2020-09-28 19:20:00Z maronga
30	! Bugfix: avoid division by zero in case of zero window fraction (now also for vertical walls).
31	! Reactivated waste heat.

47	!
48	! 4687 2020-09-21 19:40:16Z maronga
49	! Bugfix: values of theta_m_t_prev were not stored for individual surfaces and thus re-used by all
50	! surfaces and buildings, which led to excessive indoor temperatures

53	! Bugfix for implementation of downward surfaces
54	!

62	! Change order of dimension in surface array %frac to allow for better vectorization.
63	!
64	! 4441 2020-03-04 19:20:35Z suehring

67	! fluxes.
68	!
69	! 4346 2019-12-18 11:55:56Z motisi

75	!
76	! 4310 2019-11-26 19:01:28Z suehring

157	! Description:
158	! ------------
159	!> Module for Indoor Climate Model (ICM)
160	!> The module is based on the DIN EN ISO 13790 with simplified hour-based procedure.
161	!> This model is a equivalent circuit diagram of a three-point RC-model (5R1C).
162	!> This module differs between indoor-air temperature an average temperature of indoor surfaces which make it prossible to determine
163	!> thermal comfort
164	!> the heat transfer between indoor and outdoor is simplified
165
166	!> @todo Many statement comments that are given as doxygen comments need to be changed to normal comments
167	!> @todo Replace window_area_per_facade by %frac(1,m) for window
168	!> @todo emissivity change for window blinds if solar_protection_on=1
169
170	!> @note Do we allow use of integer flags, or only logical flags? (concerns e.g. cooling_on, heating_on)
171	!> @note How to write indoor temperature output to pt array?
172	!>
173	!> @bug Calculation of iwghf_eb and iwghf_eb_window is faulty
